But as I put my logo instead of writing?
Logo / Brands
Here we provide to you guys how to tweak/hack the text logo into image logo.
First at all, you have to open the index.php file that located in Wanderers directory.

Here the directory path : /templates/wanderers/index.php

Then you have to find lines of these logo/brands code

<div class="brands pull-left"> 

  <?php if($this->params->get('show_heading_title', true)) { ?>

  <h1><?php echo JText::_($this->params->get('title', 'Wanderers'));?></h1>

  <?php } ?>

</div>

Then change the <H1> code

<h1><?php echo JText::_($this->params->get('title', 'Wanderers'));?></h1>

into <img>
